For the first time, scientists have identified what they call a "house" that can store memories. In fact, this is a neuron that can store information about the geographic location of our past and present.
 
With the discovery of these special neurons, we may be able to learn more about the mechanism of brain memory formation.
 
Researchers from France introduced a fluorescent protein into the neurons of mice that illuminates at the moment of cellular calcium influx, which indicates that neurons are activating.
 
When the mouse is placed on the running table, the neurons can be activated step by step, which can indicate the mileage of their running.
 
When the mouse is resting, the neurons can also illuminate, but the frequency is significantly faster, and the illuminating part is significantly different from the running.
 
Shows that the mouse is currently in a different state of running.
 
These luminescent neurons are not closely aligned in the hippocampus of the brain, but the neurons have a clear connection to each other while running.
 
However, other researchers doubt whether the evidence can prove that these neurons are indeed units of memory.
 
According to Kamran Diba from the University of Wisconsin, the activity of mice on a treadmill is continuous, but in the brain is divided into different intervals, which seems difficult to explain.
 
In any case, the researchers acknowledged that further trials are needed to corroborate. If the phenomena we see are real, then this can deepen our understanding of the memory work of the human brain, and at the same time accelerate our development of treatments for neurodegenerative diseases.
 
Technically, this set of fluorescent protein-labeled neurons is useful because it tracks more than 1,000 neurons simultaneously.
 
Memory is a very important tool for both mice and humans, and research in this area can help us understand the mechanisms by which they work.
 
The results are published in the latest issue of Science.
